The catalyst appears as a reactant in the first step and as a product in the last step.

The intermediate is produced from the reactants and further consumed to produce the products.


step 1:      AB + C  A + BC

step 2:     AB + BC  AB2 + C

              -----------------------------------

overall:    2AB  A + B2
